Did you use an epidural or narcotic during labor and feel like it affected your baby negatively?

I'm absolutely terrified of the idea of having a second child after the experience with my first. I often wonder if the Stadol + Pitocin and Epidural I received affected my baby's HR dropping and thus causing me to have an emergency C section (especially the Stadol). I'm also upset that the doctor didn't tell me about the possible side effects of Stadol.

Anyone go medicine free, no epidural or anything? How did you do it?!
